摘　　要：银镜反应作为高中化学教学中醛基的一个重要性质演示实验,在演示时通常需要水浴加热,且形成银镜所需时间较长。在一系列实验探究的基础上,发现在银氨溶液中加入一定量碳酸钠溶液后再加入乙醛,常温下能够在较短时间内生成银镜。该反应操作简单,银镜形成较快。As an imgportant property demonstation experiment of aldehyde group in senior high school.chemistry teaching.silver mirror reaction usually required water bath heating.and it took a long time to form silver mirror.In this puper.on the basis of a senies of experimental exploration,it was found that a certain amount of sodiurm carbonate solution was added to the silver ammomia solurin.and then actalde-hyde was added,silver mirror could be generated in a short time al room temperalure.The reaction was simple to operate.and the silver mirror formed relatively quickly.
